FIELD: channel communication in mobile communication system. SUBSTANCE: achievable technical result of invention lies effective transmission of secondary scrambler codes which are utilized for increase of channel capacity in mobile communication system. In compliance with method identifier of secondary scrambler code is found on receipt of request for assignment of specialized channel from mobile station, found identifier of secondary scrambler code is sent to mobile station and response is anticipated. On receipt of reply from mobile station primary scrambler code and secondary scrambler code are generated with use of identifier of primary scrambler code and identifier of secondary scrambler code. Signal of common channel is scrambled with use of primary scrambler code, signal of specialized channel with use of secondary scrambler code is scrambled and scrambled channel signals are sent. EFFECT: effective transmission of secondary scrambler codes used to increase channel capacity in mobile communication system. 23 cl, 11 dwg
